Reaction of amine with hno2

Nitrous acid is the main chemphore in the Liebermann reagent, used to spot-test for alkaloids. Gaseous nitrous acid, which is rarely encountered, decomposes into nitrogen dioxide, nitric oxide, and water: 2 HNO2 → NO2 + NO + H2O Nitrogen dioxide disproportionates into nitric acid and nitrous acid in aqueous solution: WebHydrazine is used to convert the ester to an acylhydrazine, which is reacted with nitrous acid to give the acyl azide. Heating the azide in ethanol yields the ethyl carbamate via the Curtius rearrangement. Acid hydrolysis yields the amine from the carbamate and the carboxylic acid from the nitrile simultaneously, giving the product amino acid. [17]

WebNitrous acid (molecular formula H N O. 2) is a weak and monoprotic acid known only in solution, in the gas phase and in the form of nitrite ( NO−. 2) salts. [2] Nitrous acid is used to make diazonium salts from amines. The resulting diazonium salts are reagents in azo coupling reactions to give azo dyes . WebApr 8, 2024 · Actually the reaction of an amine with nitrous acid ( H O − N = O ) is used to identify the presence of primary, secondary or tertiary amines as each of them react in a different way with nitrous acid. Nitrous acid is unstable intermediate and is prepared instantly before the preparation of diazonium salt.
